COMMUNITY DIRECTORY
Best Subreddits, by Audience
Thirty guides to the Reddit communities where specific audiences ask buying questions out loud — what each one is actually for, and what happens if you promote in it.
Most "best subreddits" lists are a pile of names with subscriber counts next to them. That is close to useless. A community with millions of members can be worthless to you if nobody there ever asks a purchase question, and a quiet niche sub can produce a lead a week because every third thread is somebody describing a problem you solve.
These guides are organised by audience rather than by size. For each one you get the communities where that audience actually congregates, the shape of the questions that get asked there, how tolerant the community is of anyone with a commercial interest, and the phrasings that reliably signal somebody is close to buying something.
A warning that applies to all thirty pages: Reddit is not a distribution channel. It is a place where people who distrust marketing talk to each other, and every community on this list will remove you for treating it otherwise. The approach that works is narrow — read the rules, contribute where you genuinely know something, disclose your affiliation, and accept that most threads are not for you. MentionSpot exists to make the finding part fast; the contributing part is still yours.

Questions about choosing subreddits
How many subreddits should I actually monitor?
Fewer than most people start with. Five to ten well-chosen communities produce more usable conversations than fifty, because monitoring is only useful if you read what comes back. Start with the two or three where your audience clearly lives, run them for a month, and add more only when you are consistently clearing the queue.
Are large subreddits better than small ones?
Usually the opposite. Large general communities carry high volume and low specificity, so buying questions get buried. Small niche communities have fewer threads but a much higher proportion of them describe a concrete problem with a budget attached.
Can I post about my product in these communities?
Sometimes, and always on the community's terms. A minority of subreddits have dedicated promotion threads or launch days. The rest expect you to answer questions as a knowledgeable person and disclose your affiliation when your product is relevant. Posting a link with no context will be removed almost everywhere on this list.
Does MentionSpot post to Reddit for me?
No. MentionSpot is read-only. It monitors Reddit and X for conversations matching your keywords, scores each one for buying intent, and gives you a ranked queue. It never posts, comments, votes, or messages anyone on your behalf.
